Driver core: Drop __must_check from bus_for_each_drv()
There is little rationale for marking bus_for_each_drv() __must_check.
It is more of an iteration helper than a real function. You don't know
in advance which callback it will be used on, so you have no clue how
important it can be to check the returned value. In practice, this
helper function can be used for best-effort tasks.
As a matter of fact, bus_for_each_dev() is not marked __must_check.
So remove it from bus_for_each_drv() as well. This is the same that
was done back in October 2006 by Russell King for
device_for_each_child(), for exactly the same reasons.

This one depends on a previous patch (which removes SOC_AU1X00 and changes

this to go in via the mips tree.
The commit "MIPS: Tracing: Cleanup the arguments passing of
prepare_ftrace_return" has moved the "jal prepare_ftrace_return"
instruction after the handling of the 3rd argument but forgot to remove
the superfluous space before the related instructions.
Although all EMMAxxx SoCs can support IP2 and IP3 hardware interrupts,
current EMMA2RH plat_irq_dispatch() supports IP2 only. We can make it
configurable in the future, but for the time being, would like to make
things explicitly allcated to IP2 in accordance with plat_irq_dispatch().
For historical reasons, we used to put MIPS CPU IRQs behind SoC-specific
IRQs in the queue, and have been using CPU_IRQ_BASE as MIPS_CPU_IRQ_BASE.
In recent years, however, we've brought it back to normal order, and now
CPU_IRQ_BASE just redefines the generic MIPS_CPU_IRQ_BASE.
At the same time, NUM_CPU_IRQ is also removed as useless.
Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could
be replaced with a single call to sscanf(), looks cleaner to me at

over to using random_ether_addr() when an attempt to parse an invalid
MAC address is made.
